  • Image forming apparatus and method for developing electrostatic latent image
    Publication number: 20090103957
    Abstract: Provided are an image forming apparatus equipped with a hybrid developing apparatus including a toner-collecting developer-carrying member and a method for developing an electrostatic latent image, which apparatus is capable of stably forming high definition images without occurrence of a leakage current even under a high-humidity environment. In the apparatus, each of a toner-supplying developer-carrying member and the toner-collecting developer-carrying member has a conductive substrate to which a bias voltage is applied, and at least one of the surfaces of the conductive substrates of the toner-supplying developer-carrying member and the toner-collecting developer-carrying member has a resistive layer formed thereon.
